grain diameter

基本解释

Calculate the grain size from an image processed including grain-edge by average diameter method.
采用平均直径法对一幅经过处理的晶界图像进行晶粒度计算。
Turfy not too fine, pearlite grain diameter 3 - 4 millimeter, vermiculite grain diameter 3 - 5 millimeter are idealer.
泥炭不要太细，珍珠岩颗粒直径3-4毫米，蛭石颗粒直径3-5毫米比较理想。
Based on analysing the gravel features, several non-conventional porosity laboratory prediction methods, such as CT scan, image analysis, grain statistics, full-diameter analysis, have been described.
在总结分析砾岩特点的基础上，简要介绍了包括CT扫描、图象分析、粒度统计、全直径分析等几种非常规孔隙度实验估测分析方法。
